Trial Report



Trial Number 10

(Client Number 341, Project Number 1)

Trial Purpose: To evaluate three supplied products for glass cleaning as part of three part experiment to evaluate product

Date Run: 06/01/11

Experiment Procedure:
Supplied products were used at the recommended dilution (2.4%). Pre-weighed mirror, glass, and chrome plated aluminum coupons were coated with SSL Soil 2 (Glass soap scum: Water, hair gel, toothpaste, shaving cream, hair spray and spray deodorant) using a hand held swab and allowed to dry for 24 hours at room temperature. The contaminated coupons were weighed again to determine the amount of soil added.
Three coupons were placed into a Gardner Straight Line Washability unit. A Wypall X60 reinforced wipe was attached to the cleaning sled and soaked with 5-7 sprays of cleaning solutions. Each coupon was sprayed 7-10 times with the same cleaning solution. The solution was allowed to penetrate for 30 seconds followed by cleaning in the SLW unit for 5 cycles (~10 seconds). At the end of the cleaning, coupons were wiped once with a dry paper towel. Final weights were recorded and efficiencies recorded.

Trial Results
All three products were effective for glass cleaning, removing more than 85%. The DFE 401 indicated low cleaning effectiveness on mirror surface than
other cleaners. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating
A follow up test, usually based on company input.

Conclusion
All of the supplied products removed over 85% of the soil. The PC 101 had the highest removal efficiency and was the only product to be effective on all three soils for the three cleaning tasks.
